The Keystone XL Pipeline project is 'owned by TransCanada, a Canadian corporation' that builds, maintains, and owns oil and gas pipelines, power plants, and natural gas storage facilities IN NORTH AMERICA......BTW TransCanada 'already 'owns" the Keystone Pipeline. Further the only reason Canada went this way was because their own people 'voted down' the initial plans of putting it in their own country'.
"The project will create no more than 2,500-4,650 "temporary" direct construction jobs for two years,according to TransCanadas own data supplied to the State Department,"................... estimate of the number of "permanent" jobs that could be created by work on the pipeline to be about 50 to 100.
All predictions for spinoff jobs, as you mentioned, rely on factors like the price of oil, energy innovation, politics, and the overall health of the economy. Furloughs happened to many when the oil price went down. and again....Trans Canada will employ their own people FIRST, who move from site to site throughout the states, then 'private contractors' and employment agencies to hire the "temporary workers"...good for about two years.
so what?
it ibusiness that makes the world go round
See my Comment #1094 for other concerns about the pipeline(s). Yes, they did want to build to the Pacific, but there was a lot of opposition, so yes, it is slated for overseas markets, not ours.
Looking at the chart it appears the University study was for a lot fewer jobs even than the US govt. study which was lower that the TransCanada estimates which have also shrunk over time (too much sunlight on those figures?).
